RobotGrrl’s Lightning LOL Necklace is both an electronics enclosure and the diffusing faceplate to produce the effect!
The inspiration for the face plate idea came from Buddy 4000. We noticed that the light can shine though its plastic, because of the low infill percentage, so figured the same would be true if the design was only 4 layers (and 2 layers on the lightning bolt).
There was one point where this whole project didn’t work. When soldering the Diavolino and LoL Shield together, the height must have slipped- which caused the reset button to always be pushed. Somehow we were able to desolder this… even though it was tightly squished between the two. Phew!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
